Morito moved quickly to pull the red-headed girl who'd been following him out of the way of the imminent explosions and battling. The martial artist girl seemed to be in some sort of...traumatized cat-trance and looked about close to snapping under the stress of it. The mercenary had seen berserker rages and breakdowns of all kinds before, so he decided to act as fast as possible to halt this one before the obviously durable girl got herself hurt for real regardless. He grabbed Ranma by the shirt and attempted to half-haul half-throw her out of the way while hurling himself aside along with her to try and avoid both the dragon's pouncing attack and yet another concussive explosion from the flying girls above them.

Figuring that the cat-fearing girl's freaked out state would persist after being removed from the immediate presence of the panther-dragon, he threw a few of the spikes he'd retrieved earlier to attempt to pin Ranma to a tree by her clothes as they both flew through the air, confident as he was in his skill at knife-throwing and hoping he wouldn't have to otherwise physically restrain her. He hit the ground and rolled, coming up as he did with another set of spikes in his hands and closing his eyes. His sight was obviously going to be of limited use against an enemy who could turn invisible, so he turned to his other senses to guide him.. 

Fortunately, Morito had long ago sharpened his hearing to the limits of human potential. Combined with years of study and discipline, he was able to form a highly accurate mental sonar map using just the noises of the environment and occasional clicks from his tongue, even achieving a sort of X-ray effect if he focused enough. With his 'ELS' skill, while the panther-dragon might be invisible to the eye as long as sound waves still bounced off of it, Morito could see it and fight it.

That is, if those blast-happy girls above him didn't utterly destroy the Nargacuga with Love and Friendship. The mere thought made the seasoned vet shiver.
